Bertie : just like Daddy / Marcus Pfister.

Enhanced descriptions from Syndetics:

Bertie, a little hippo, expresses the universal desire to do the things his dad does as they spend a day together. Daddy always has wise and gentle words in reply to his son's requests: "'I want to shave,' says Bertie. 'Just like you.' 'Will you settle for some shaving cream?'" his father asks. "'Give me a white beard,' says Bertie." The simple text has a cheerful refrain, "Just like you." The tables are turned at the end when Daddy asks to do what Bertie does--play with a train because he wants to be a kid again. The bold, expressive illustrations are embellished with multihued flowered patterns, in counterpoint to the hefty gray hippos.
